Legal Consequences of Israel’s Prolonged Occupation: Analyzing the 2024 ICJ Advisory Opinion

Publications, Research paper

ABSTRACT

The International Court of Justice (ICJ) gave an historic advisory opinion in 2024, which maintained that Israel’s occupation of Palestinian lands since 1967 is against international law. This paper addresses the legal basis of the ICJ decision, its implications for state responsibility, and its broader implications for international law. The weakness of advisory opinions to shape international legal and diplomatic policies is also considered, along with potential measures for enforcement. In an attempt to make the topic current with contemporary debate in international law, the research further delves into historical context, geopolitical reactions, enforcement challenges, and other legal remedies.

INTRODUCTION

Global deliberations for quite some times have concentrated on the conflict between Israel and Palestine and the alleged illegal occupation by Israel of the West Bank, Gaza Strip and East Jerusalem. Israel’s ongoing occupation remains in contravention of fundamental international law such as the principle of self-determination, and the annexation of territory “ICJ 2024 advisory opinion”. This thesis deals with the legal basis of the ruling, its international legal ramifications, and the possible impact on Israel, Palestine and Israel’s neighbors. This ruling is also important for the impact of international enforcement of due compliance with international law and the increasing legal barrier to defamatory international occupation. This paper analyses some important legal documents which constitute the basic foundation for the decision of the ICJ namely UN Charter (1945) on self-determination, Fourth Geneva

Convention (1949) on the treatment of populated territories, and other previously decided cases of the ICJ, like Namibia Advisory Opinion (1971) and another Wall A 2004.

The research focus and question of this paper is “What are the legal implications of the 2024 ICJ advisory opinion on Israel’s occupation of Palestinian territories, and how does it impact international law and enforcement mechanisms?”

RESEARCH METHODOLOGY

This study employs a doctrinal legal research methodology, focusing on primary and secondary sources of international law. The research is based on an in-depth examination of legal texts, case law, and scholarly interpretations to evaluate the ICJ’s advisory opinion.

  • Primary sources

Treaties, conventions, UN resolutions, and past ICJ rulings, particularly the UN Charter (1945), Fourth Geneva Convention (1949), ICJ Namibia Advisory Opinion (1971), and Wall Advisory Opinion (2004). These documents provide the legal framework for understanding the ICJ’s 2024 ruling and its implications for state responsibility and international law.

  • Secondary sources

Academic journal articles, books by legal scholars, reports from international organizations, and expert commentaries on international humanitarian law.

REVIEW OF LITERATURE

Eyal Benvenisti “The International Law of Occupation”, 2012 defines and critiques the scope of obligation of occupying powers under humanitarian law. Prolonged occupation, in Benvenisti’s view, is a de facto annexation in which the distinction between military control and civilian rule is suppressed. Although this book is important in understanding the way international law govern occupation, it fails to address the political realities that make legal decisions unenforceable.

Antonio Cassese, “International Law” (2005), explains the state responsibility and territorial acquisition by force as the basis for some other state norms. He is rather important for the

understanding of the legal norms which the ICJ used in its opinion of 2024. Nonetheless, his book fails to address the sanctions or third state participation in the occupation’s maintenance.

John Dugard, “International Law and the Israeli-Palestinian Conflict” (2009), tackles the legal aspects of Israeli occupation. He claims that some districts of West bank are governed under the apartheid regime. While his view is reasonable under the scope of Israel’s legal obligations, his focus solely rests on the sphere of human rights law and not on the geopolitical enforcement. My research fills this gap by combining Dugard’s critique with the consideration of state responsibility and the enforcement of that responsibility by the international community.

Richard Falk, “Palestine: The Legitimacy of Hope” (2014), speaks about the moral and legal issues of the Israeli-Palestinian dispute in terms of international law and particularly the human rights approach. He is as well an important voice of the Palestinian struggle against occupation.

Michael Lynk, Special Rapporteur on Palestine for the UN from 2017-2022, meticulously details human rights violations in the occupied territories and evaluates Israel’s actions regarding international humanitarian law in his reports. Lynk’s reports offer invaluable empirical evidence that buttresses the legal claims advanced in this study. Nonetheless, they remain explanatory as opposed to prescriptive in their therapeutic legal analysis. This thesis expands on Lynk’s work by suggesting therapeutic mechanisms to enforce ICJ decisions and increase responsibility of the third parties.

In the Journal of Conflict and Security Law, Shawan Jabarin et al. published “Accountability for Israeli War Crimes” in 2023, which makes the case for ICC action on the issues of settlement activity, military aggression, and so-called ‘soft’ human rights violations. Jabarin is, of course, correct, but he fails to take into account the prosecution of systematic domination and its associated crimes as an integral part of the implementation of the Rome Statute. His work, however, does not analyse the impact of advisory opinions, as opposed to contentious ICJ judgments, on the workings of the ICC. My research fills this void by exploring the potential of the 2024 ICJ opinion in establishing the groundwork for future prosecutions of war crimes.

While these works provide significant insights into the legal, political, and human rights

dimensions of the Israeli occupation, they leave critical questions unanswered—particularly regarding the enforceability of ICJ advisory opinions, the influence of international political dynamics, and the role of third-party states in perpetuating or challenging occupations. This research fills those gaps by offering a comprehensive legal and geopolitical analysis, evaluating how legal precedents, state behavior, and institutional frameworks intersect in the enforcement of international law.

LEGAL BASIS

The legal parameters of the ICJ’s 2024 advice opinion rests on existing international law practices based on treaties, conventions, and case law. It incorporates legal instruments such as the UN Charter (1945), the Fourth Geneva Convention (1949), the ICJ Namibia Advisory Opinion (1971), the Wall Advisory Opinion (2004), various UN Security Council and General Assembly Resolutions, and the Rome Statute of the International Criminal Court (1998) pertaining to the occupation. Each of these instruments posits the legality of the occupied Palestinian territories and the responsibilities of state and non-state actors under international law relating to the Israel occupation of Palestinian territories.

  • The Right to Self Determination and The UN Charter (1945)

Particularly Article 1 (2) and Article 55 of the UN Charter incentivizes self- determination as a principle of legal entitlement reiterating that people may determine their political status without interference. The right to self-determination is widely accepted as a norm of jus cogens – an order that is peremptory and cannot be relaxed. The self-determination norm was reinstituted by ICJ when it confirmed that Israel’s occupation of Palestinian territories restricts this right which serves as a violation of the Israel legal arrangement and framework which rests on the principles of the UN. Denying self-determination through occupation and settlement expansion to the Palestinians by Israel contradicts international law principles.

  • Fourth Geneva Convention (1949) and the Law of Occupation

The Fourth Geneva Convention, particularly Articles 27-34 and 47-78, governs the treatment of civilians under occupation. It explicitly prohibits annexation, the transfer of an occupier’s civilian population into occupied territory, and collective punishment of protected persons. The ICJ cited Israel’s settlement policies, land confiscations, and

restrictions on Palestinian movement as violations of these provisions. This legal framework is instrumental in determining the humanitarian obligations of an occupying power and serves as the foundation for assessing the legality of prolonged military control over another people’s territory.

  • Occupation

In the Namibia Advisory Opinion, the ICJ ruled that South Africa’s continued administration of Namibia, despite UN resolutions terminating its mandate, was illegal under international law. The Court held that prolonged occupation without a valid legal basis and against the will of the international community constitutes an unlawful act. This precedent directly applies to Israel’s occupation of Palestinian territories, reinforcing the argument that an occupying power cannot derive sovereignty over the occupied land and must withdraw when its control is deemed illegitimate by the international community.

  • ICJ Wall Advisory Opinion (2004) and the Illegality of Unilateral Actions the Wall Advisory Opinion found that Israel’s construction of a security barrier in the West Bank violated international humanitarian law and human rights law, as it facilitated de facto annexation of Palestinian land. The ICJ ruled that the construction was not justified by security needs and constituted a breach of Israel’s obligations under the Fourth Geneva Convention and human rights treaties. This precedent underscores the broader legal implications of unilateral measures taken under the guise of security but resulting in permanent territorial changes.
  • UN Security Council and General Assembly Resolutions

A series of UN Security Council Resolutions (e.g., Resolutions 242 (1967), 338 (1973), and 2334 (2016)) have affirmed the inadmissibility of acquiring territory by force and called for Israel’s withdrawal from occupied territories. Resolution 2334 (2016) explicitly states that Israel’s settlements in Palestinian territory have no legal validity and constitute a flagrant violation of international law. The ICJ incorporated these resolutions as legal evidence reinforcing the international consensus that Israel’s continued occupation and settlement expansion are unlawful.

  • Rome Statute of the International Criminal Court (1998) and War Crimes

The Rome Statute, which governs the International Criminal Court (ICC), defines war crimes under Article 8, including the transfer of an occupier’s civilian population into occupied territory. The ICC has jurisdiction over crimes committed in occupied territories, and in recent years, it has launched investigations into Israeli settlement expansion, military actions, and alleged human rights abuses in Palestinian territories. The ICJ’s ruling strengthens the legal grounds for potential ICC prosecutions, further reinforcing Israel’s legal obligations under international law.

POLITICAL AND LEGAL IMPLICATION

For Israel, the ruling could result in increased international legal scrutiny and potential sanctions. The decision may also strengthen cases at the ICC regarding war crimes and human rights violations associated with settlement expansion and military operations in occupied territories. Additionally, Israel may face diplomatic and economic repercussions, as states and international organizations may impose restrictions or withdraw support for its settlement policies.

For Palestine, the ruling provides a legal foundation to push for full UN membership and recognition. The ICJ’s opinion strengthens Palestine’s claims in international legal forums, potentially leading to restitution and reparations for damages caused by the occupation. Beyond Israel and Palestine, the ruling sets a precedent for addressing other prolonged occupations, such as Russia’s occupation of Crimea and Morocco’s control over Western Sahara. The opinion reinforces the principle that occupation cannot lead to sovereignty and raises concerns over the enforceability of international legal rulings in cases where the occupying power refuses to comply.

Furthermore, the ruling could encourage states and international organizations to take independent legal action against Israel, including trade restrictions, diplomatic measures, and targeted sanctions. The European Union, for example, has already debated policies to restrict imports from Israeli settlements, and the ICJ ruling may further push for formal legal action at the international level. The case also highlights the evolving role of international legal

institutions in territorial disputes, emphasizing the growing influence of non-binding judicial opinions in shaping global diplomatic strategies.

CHALLENGES IN ENFORCEMENT

ICJ advisory opinions are legally influential but not binding. Enforcement relies on political will and international pressure, making their practical impact limited in conflicts involving major geopolitical actors. Unlike ICJ contentious cases, advisory opinions do not impose direct legal obligations. Their enforcement depends on voluntary compliance and diplomatic actions, often leading to selective adherence based on political interests. The United States and European Union’s political and economic ties with Israel may prevent meaningful enforcement, further reducing the likelihood of any substantial consequences arising from the ICJ’s ruling.

Additionally, the divided stance among Arab and Muslim-majority nations on direct confrontation with Israel weakens collective diplomatic pressure that could otherwise be used to enforce the ruling. Without a coordinated international response, Israel is unlikely to face significant legal consequences, further highlighting the challenges in translating international legal principles into enforceable actions. Another major challenge is the inconsistency of enforcement mechanisms in international law, where politically powerful states can ignore or selectively apply legal rulings without facing significant repercussions. This inconsistency weakens the credibility of institutions such as the ICJ, reinforcing the need for legal and institutional reforms to ensure compliance with international law.

POTENTIAL IMPACT ON INDIA’S LEGAL AND DIPLOMATIC LANDSCAPE

The ICJ’s advisory opinion may influence India’s legal and diplomatic positioning in several ways. While India has historically supported Palestinian statehood and emphasized the inadmissibility of acquiring territory by force, it also maintains strong diplomatic and defense ties with Israel. The ruling creates a potential dilemma for India’s foreign policy, as it balances its commitment to international legal norms with its strategic partnership with Israel in areas such as defense, cybersecurity, and trade.

From a legal perspective, the ICJ ruling may set a precedent for India’s stance on territorial disputes, including Kashmir. Although India considers Kashmir an internal matter, Pakistan has frequently invoked international legal mechanisms to challenge India’s sovereignty over the region. If India endorses the ICJ’s position on Israel’s occupation, it may face reciprocal diplomatic and legal challenges from adversaries using the same legal arguments to question its territorial claims. Conversely, if India rejects the ICJ ruling or remains silent, it may weaken its historical support for self-determination movements, including that of Palestine.

Moreover, the legal principles reaffirmed in the ruling—such as the prohibition of annexation, the role of military control in occupied territories, and the recognition of self-determination— may shape India’s approach to international dispute resolution. Indian courts, particularly the Supreme Court of India, may reference ICJ jurisprudence when dealing with cases involving international humanitarian law, state sovereignty, or obligations under treaties such as the Geneva Conventions.

On the diplomatic front, India may advocate for a balanced approach, continuing its support for a two-state solution while strengthening trade and security ties with Israel. The ruling may also affect India’s engagement in the United Nations Human Rights Council (UNHRC) and the UN General Assembly, where it has historically voted in favor of Palestinian rights. Any shift in India’s voting pattern or diplomatic stance may be scrutinized by both Western allies and the Global South, particularly the Arab world, which remains a crucial partner for India’s energy security and expatriate labor markets.

SUGGESTIONS
  • Strengthening Third-State Obligations

A crucial step toward enforcing the ICJ’s advisory opinion is holding third-party states accountable for their role in sustaining or opposing the occupation. Countries providing military, economic, or diplomatic support to Israel must be scrutinized under international law. For example, the United States has provided billions of dollars in annual military aid to Israel, which indirectly supports the settlement expansion and military presence in occupied territories. By implementing strict arms embargoes or conditional foreign aid policies, third-party states can reduce material support for actions deemed illegal under international law.

Additionally, European Union trade policies could be revised to prohibit imports from Israeli settlements, similar to EU restrictions on goods from Crimea following Russia’s annexation in 2014. International trade laws, such as the Generalized System of Preferences (GSP), could be leveraged to impose economic consequences on Israel for non-compliance with international law. Furthermore, the Boycott, Divestment, and Sanctions (BDS) movement has gained traction as a civil-society-led effort to exert economic pressure on Israel. While controversial, similar measures were historically effective in dismantling apartheid in South Africa.

  • Resolutions and Actions of the UN General Assembly and their Diplomatic relations

Certainly, in as much as member nations of the UN Security Council exercise veto power, notably the US, the UN General Assembly can still ensure the enforcement of the ICJ opinion. The UNGA has previously passed resolutions condemning Israeli settlement expansions and calling for Palestinian self-determination. For example, in 2004, the Assembly passed resolution ES-10/15 which denounced the construction of the wall of the West Bank and termed it illegal. Future resolutions could be more progressive in recommending economic sanctions or suspension of Israel’s privileges at the UN until such time that international law is adhered to.

  • Improving ICC Prosecutions and Its Legal Mechanisms

The International Criminal Court (ICC) has jurisdiction over war crimes, including the unlawful deportation or transfer of civilian people into occupied regions as provided in Article eight of the Rome Statute. The Court has already opened investigations into the crimes committed in the Palestinian territories, but enforcement remains a challenge due to Israel’s non-recognition of the International Criminal Court’s jurisdiction. In order to reinforce the ICC’s actions, the state parties to the Rome Statute ought to advocate for arrest warrants for Israeli officials who actively participate in settlement policies. Similar attempts were done in 2023 where the ICC put an arrest warrant on Vladimir Putin for the alleged war crimes in Ukraine.

Also, universal jurisdiction statutes in several countries could serve to prosecute persons culpable of war crimes. In 2015, Spain’s universal jurisdiction law permitted action against some former Israeli officials for the purported violation of human rights.

  • Increased circumvention of such legislation may serve to put greater constraints on Israeli leaders to adhere to the internationally accepted legal standards.

Moreover, regional diplomacy constituencies require special attention. The Arab League, OIC, and AU could adopt a stand in unison to diplomatically pressure Israel. An example for such regional action includes the African Unions 1984 decision during the time of apartheid South Africa to withdraw its observer status. Such actions demonstrate how regional blocks can diplomatically alter world relations. Applying this logic to Israel’s observer status in the international forums would raise the political price for occupying Palestine.

  • Economic Sanctions and Financial Pressure

Economic sanctions have historically been effective in changing state behavior. The United Nations and the European Union have previously imposed sanctions on countries violating international law, including Russia (Crimea annexation) and Iran (nuclear program violations). Applying targeted sanctions against Israeli officials, businesses operating in illegal settlements, and financial institutions funding settlement expansion could create tangible economic consequences for non-compliance with the ICJ ruling.

Another potential avenue is freezing assets and imposing travel bans on Israeli officials involved in settlement construction and military operations in occupied territories. Similar measures were implemented against Russian oligarchs following the annexation of Crimea. Financial institutions could also face restrictions under the Foreign Corrupt Practices Act (FCPA) and Anti-Money Laundering (AML) regulations if they are found complicit in funding illegal settlement activities.

  • Strengthening Palestine’s International Legal Standing

Palestine currently holds non-member observer state status at the UN, which limits its legal and diplomatic influence. Granting full UN membership would significantly strengthen its ability to engage in international legal processes. The 2012 UNGA Resolution 67/19 recognized Palestine as a non-member observer state, a step toward full recognition. The next step should be lobbying for full UN membership, requiring a two-thirds majority vote in the UNGA and approval by the Security Council.

Moreover, Palestine should seek membership in additional international organizations, such as the World Trade Organization (WTO) and International Monetary Fund (IMF), to solidify its international legal presence. This would allow Palestine to engage in international economic and trade disputes, further legitimizing its status as a sovereign entity under international law.

  • Grassroot and civil society movements

Legal and diplomatic actions must be complemented by grassroots advocacy and civil society initiatives. International organizations such as Human Rights Watch (HRW) and Amnesty International have played a vital role in documenting human rights violations in occupied territories. Increased collaboration between Palestinian human rights organizations and global advocacy groups could amplify pressure on international institutions to act.

Educational institutions and academic bodies should also play a role in raising awareness. University-led campaigns, similar to the anti-apartheid movement in the 1980s, could influence public opinion and corporate policies regarding investments in Israel.

Additionally, digital activism through social media campaigns, petitions, and online awareness programs has proven effective in influencing international narratives. For instance, the #SaveSheikhJarrah movement gained significant global attention in 2021, pressuring governments to take a stand against forced evictions in East Jerusalem.

CONCLUSION

This judgement serves to accomplish a landmark in legal history in regard to self- determination, prohibition of territorial acquisition by violence, and state responsibility in self- regulation. Although the opinion itself is non-binding, it’s impact goes far beyond the immediate Israel-Palestine case in international governance, legal precedents, and bilateral relations, which is not the case in this argument’s premise political integration. global comes to all to all extend of global politics participation enhances monopolized control power without power dualism universal have assumed.

One of the most important lessons to learn from governing structures is to annex territory which is under occupation for a long time. Drawing from the foundation of international legal

documents such as UN Charter, Fourth Geneva Convention, and previous determinations made by the court, The Court has restated the components of the obligations of Israel under the international law. Nonetheless, ruling remaining useful to those willing to enforce its principles even by diplomatic, economical, or legal actions proves very little to those accepting diplomatically.

The ruling has consequences for India as well, because India has historically backed the self- rule of the Palestinians while having cordial relations with Israel. India’s policies on territorial conflicts, participation in international legal processes, and assignment of diplomatic roles at the United Nations are likely to be affected by wider legal norms which the International Court of Justice (ICJ) has affirmed in its ruling. Whether India supports the reasoning of the ICJ or takes a more pragmatic, self-interest approach will determine how the country will participate in international legal discourse in the years to come.

As for what needs to be done, the international community ought to start implementing the legal aspects of the ICJ ruling. These include: strengthening the obligation of third states not to take actions that would contravene towards assisting in illegal occupations, enforcing selective economic sanctions, broadening the ICC prosecution scope, granting Palestine full membership to the UN, among other things, will lend legal weight to the findings of the advisory opinion. Mobilization at the grassroots was needed, along with the need of civic advocacy for human rights and international law compliance, as any non-compliance has legal obligations and consequences.
